4. You Eat a Lot of Grains

Even whole grains can increase your acidity; if most of your food is carbohydrates and grain based, you could be suffering from excessive acid levels. Corn, white flour and even whole grain consumption can cause your acid levels to rise and make it more difficult for you to achieve a balanced pH. While fiber and grains are building blocks of a good diet, going overboard and eating just grains could impact your acid levels and lead to a variety of complaints.
